Salaam Alaykum
I left couple of pictures last time and commented them. Somehow a friend of mine (Aamir) took it the wrong way and some how assumed that I am calling someone Kafir (disbeliever). Aamir I never used that term so please be careful before you pass you verdict on anyone. And I also didnt speak against visiting graves but I am against the reason graves are visited in pakistan, specially of the saints and scholars of islam. For your information I do believe in Tawassul as I practice it in my life, Alhamdulillah. You wrote a long commment blamming me of this that. I will try to put forward the true essense of Tawassul in Islam. Its true meaning in Islam taught by the Prophet Mohammad PBUH and practiced by his Sahabha.
This is a small answer to all the long comments you wrote. Its an answer by a scholar and not my own "Vague knowledge" about Tawassul. Thats all i am gonna say about this topic. May Allah guide us to the Right Path. Path that He revealed to Prophet Mohammad PBUH and the Path our beloved Prophet PBUH told us to walk. Ameen!


What is meant by tawassul and waseelah is following things:

1. The kind of tawassul without which faith cannot be complete, which is seeking to reach Allaah (tawassul) by believing in Him and His Messengers, and obeying Him and His Messenger, This is what is meant in the aayah (interpretation of the meaning):
   “O you who believe! Do your duty to Allaah and fear Him. Seek the means of approach to Him…”
   [al-Maa’idah 5:35]
   This includes seeking to approach Allaah through His Names and Attributes, or by doing acts of obedience and worship by which one seeks to approach Allaah, and so on.
   
2. Seeking to approach Allaah by asking His Messenger (peace and blessings of Allaah be upon him) to make du’a’ for one during his lifetime, and the believers asking one another to make du’aa’ for one another. This follows on from the first type and is encouraged.
   
3. Seeking to approach Allaah by virtue of the status and virtues of some created being, such as saying, “O Allaah, I ask You by virtue of Your Prophet” and so on. This is allowed by some of the ‘ulama’, but this opinion is da’eef (weak). The correct view is that it is definitely haraam, because there can be no tawassul in du’aa’ except by virtue of the Names and Attributes of Allaah.

Tawassul as it is understood by many of the Muslims of later times, which is calling on the Prophet (peace and blessings of Allaah be upon him) and seeking his help (or seeking the help of the dead and so-called awliya’). This is a form of major shirk, because calling on or seeking help from anyone other than Allaah with regard to something that that only Allaah is able to do is a kind of worship, and directing worship to anyone or anything other than Allaah is major shirk. And Allaah knows best.
